AUTOMATIC MIXER FOR BEVERAGE-VENDING MACHINES.

Application filed may 10, 1922. Serial no 559,942.-

To all-whom it may concern:

that I,

Be it known United FIELD, a citizen of the mg at DANIEL J. BUTTER- States, resid- Los Angeles," in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Automatic Mixers for Beverage-Vending Machines, of which the following is a speciiication, reference accompanying drawings.

This invention relates to mixer for beverage the object of the invention is of simple and the mixing of, preferably, ter with a syrup, prior to being had therein to the an automatic vending machines, and

the provision eilicient means for facilitating carbonated wadischarging the mixture in a suitable receptacle.

This invention relates to certain lmprovements, hereinafter described, the apparatus disclosed in my States Patent, No. 1,407,838, ruarv 28th, 1922.

pertaining to prior United issued FeblVit-h the foregoing and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as Wlll be hereinafter described,

illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

taken on line c direction of Referring to the drawings by numerals, 1

designates the frame or casing of a vending machine upon which is mounted a casing 2.

Mounted on casing 2 is a measuring container municates, through pamage 1,-

The passage 4: opens formed between partit-erior of casing 2. into compartment 5 tions 6 and 7 Additional par 7 a are formed in the casing. ably mounted on other end is a valve head 9, end is provided with a button partition 6,

while its inner glass, syrup- 3, which container comwith the intitions 6 and A rod 8 is slidand on its 10. Mounted upon rod 8. between partition 6 and button 10, is spiral spring 11.

This spring 11 serves to hold valve head in a seated position upon partition 6, preventing carbonated water into the auxiliary pipe 12.

thereby normally from passing A front rod 13 is slidably mounted upon. partition 7 and is provided, at its inner end, with a valve head 14; that is adapted to abut against button 10 when the operator pushes upon the push button 15 attached to the outer end of the rod 13. A coil spring 16 is mounted upon rod 13 between push button 15 and partition '7. A compartment 17 is formed between partitions 7 and 7 and a primary pipe 18 communicates, at its inner end, with the compartment 17.

A mixing casing 19 is positioned close to casing 2. This casing 19 is closed at one end by a threaded plug 20 and has in its other end an apertured partition 21. Threaded into casing 19, contiguous to partition 21, is an outlet nozzle 22. The nozzle 22 is adapted'to discharge into a suitable receptacle when the receptacle is placed under the outer end of the nozzle (not shown). The auxiliary pipe 12 is con.- nected to the casing 19 and opens upon an inclined passage 23 that is adapted to permit water to strike at an angle against the rotary mixer 24, mounted within casing 19. The primarypipe 18 permits syrup to pass therethrough and be discharged against the propeller-like blades of the rotary mixer 24, whereupon water and syrup will be efficiently mixed in the casing 19 and thence through pipe 18 into the mixing casing, and at the same time, by reason of the valve head 14 striking against the button 10, carbonated water will pass from casing 2 into the auxiliary pipe 12 and thence into the mixing casing, where the syrup and water will be mixed and thence passed through the sieve or apertured partition 21 into the nozzle, in a thoroughly mixed condition.

While 1 have described the preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, .and I, therefore. reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claim.

What- I claim is:

In a device of the class described, the combination with a valve casing provided with a plurality of valve controlled passages, of a mixing casing, pipes connected to said mixing casing and in communication with said valve controlled passages of the valve ltd tured partition Within said mlxing casmg, I

and an out-let or discharge nozzle threaded at its inner end into one end of the mixing easing, substantially as shown and described. I 10 In testimony whereof I hereunto affix my signature.

I DANIEL BUTTERFIELD,
